Application filed February 10, 1912. Serial No. 676,750.

To all whom it may concern Be it known that I, TIMOTHY P. CAN? FIELD, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain My invention relates to condensers for in steam heating systems and is particularly directed to the improvement of that type and embodying a continuous receiver such as are commonly used for heating houses and the like. It resides primarily in an attachment to this continuous receiver which cooperates in conjunction with the steam return pipes in a manner toelfectually condense the steam return substantially at its point of entrance to the said receiving chamher. The device ,is particularly applicable to steam heating systems utilized in glass houses, although not limited thereto, and the improvement produced thereby resides in the insurance of complete condensation of the steam at about its moment of entry into the receiving chamber, which results in greatly lowering the pressure within such chamber and facilitating the admission of the said return steam to the said receiving chamber. An appreciable drawback hither to, has been the eifect had by the steam within the receiving chamber in retarding the admission of the returned steam. This has resulted because of the lack of complete condensation of the steam before its entry into the steam receiving chamber.

My invention therefore contemplates the provision of means for joining the return pipes at their point of admission to, the receiving chamber and maintaining a cold water spray within this means of joining, serving to elfectually condense the steam at or about the moment of its admission to-the steam receiving chamber. 1

The preferred embodiment of my invention is shown in the accompanying drawings, in which similar characters of reference designate corresponding parts, and in which Figure 1 is a side elevation of my receiving tank and adjacent appurtenances, Fig. 2 is a detail in section of the spraying cap utilized in connection with my improved spraying attachment, and, Fig. 3 is a plan view of the structure shown in Fig. 2.

her.

In the drawings, the receiving tank is shown at 1 and such receiving tank carries a water gage 2, a steam gage 3and a fourway pipe connection 4 serving as a means of communication between-return pipes 5 and the receiving tank 1. The receiving tank further provided with. a branch pipe 6 which connects with a boiler feed pump 7 whereby the waterof condensation within the receiving tank, may be drawn. therefrom and pumped into the boiler.

Carried by the four-way pipe'connection tby means ofthre'aded collars 8 and 9 or in any other preferredmanner, is a pipe 10 externally threaded as at l l for adjust ably fitting within the collar 9 and having a nozzle cap 12 thereon provided with a series of radial outlet ports 13and concentrio axial ports 14:. i Y

The steam from the system is returned through the pipes 5 to the pipe connection sand upo'n'reaching the same is almost immediately subjected to a spray of cold water emitted from the ports 13 and '14: of. the nozzle 12, this spray ofcold water being of course thrown in a manner to completely fill the tubular formation 15 through which the return steam necessarily passes. In-

evitably, the "steam is thoroughlycondensed by this spray of cold water andv being con verted into water readily passes into the receiving chamber. Inasmuch as the spraying action is continually in action, no steam enters the receiving tank for the reason that all of the returned steam must first pass through the spray oficold water and is thoroughly condensed thereby.

It will be seen that I have provided a simple attachment for receiving tanks of completecirculation steam heating systems which insures the complete transformation of returned steam to water at a determinate point in the system and thereby decreases the pressure in the tank by forming a partial vacuum, which further tends to draw the returned steam into the receiving cham- It willv be seenthat .Ihave provided a gravity return system for steam heating plants, wherein the required pressure for forcingthe returned steam into the receiv' ing chamber is comparatively small; It is well understood that a system of this type, requires a considerable pressure for maintaining a circulation and even this considerable pressure is frequently very poorly ef quently very little condensed and ofi'ers considerable resistance to the further entrance of steam and to a consequent perfect c1rcu latlon.

receiving chamber in its original for1n, since the spraying device at the point or" admission practically insures condensation. will be also understood that I am enabled to effectually utilize the exhaust steam from the pumps in my system.

hat I claim, is

1.

In condensers for steam heating systems, the combination with a receiving tank for the water ot condensation and condensing water, a four-way pipe fitting located in proximity to and above said tank with oneof its openings in direct communication therewith, return steam pipes connected with lateral diametrically opposite openings in said fitting, and a spray pipe 'adjustably YVith my apparatus, it becomes lJlTdCtlCitl impossibility for steam to enter the I mounted in the opening in said fitting diametrically opposite the tank connection, said spray pipe having radial and axial perforations whereby the condensing water will be discharged :into both of the meeting streams of steam and directed through the tankconnection into the tank and said spray pipe may be adjusted toward and from the tank connection.

3.
